The second issue is authentication. For Aadhaar to succeed in transferring benefits to the deserving poor, the primary concern must be to ensure that people who are illiterate and in far-flung areas should not be left out because they are unable to participate in a technical process. What happens when there is no electricity or internet connectivity in a truly remote area? Currently a ration shop owner in such a place can look at a ration card and deliver. But what happens when authentication via Aadhaar fails because of lack of connectivity? The head of Aadhaar has told this newspaper that a technology option that can be examined is the use of a "one-time password" received over a cellphone (the national network coverage is now extensive). This very usefully takes forward meeting the authentication challenge for all. Then, of course, there is the physical Aadhaar card which should be useful in case all else fails in ensuring authentication. Today's technology frontier offers one other option. If a Wi-Fi network covers the entire country, then using a data connection to secure authentication will not be a hurdle anywhere.
The third issue to sort out is about the Aadhaar authorities getting paid for the use of the process or data by private players. Microfinance organisations, for example, prefer to lend only to people with two identifications, one of them being Aadhaar. Can an individual ask for a share of the revenue that Aadhaar earns by allowing use of her individual data? Even more interestingly, can the Aadhaar authorities charge a fee from private developers of apps which seek to extract value from the Aadhaar data base? These open questions must be deliberated upon openly and transparently by the authorities concerned even as the operational details for implementing Aadhaar under a new legislative framework are finalised.
